Ladders are manufactured from section insulating fiberglass plastic.
Ladder consists of two ladder's elements connected one to other by means of lateral gearing swivel blocks selling in engagement with the catch which represents axis with thread and catching handle which enables to change slope angle ranging from 1800 to 00 with the pitch 150.
Construction of the catch provides necessary force for connecting and releasing ladder's elements,
which not exceed 100 N.
The stages of the ladder's elements have trapezoidal form, which provides horizontal position of supporting surfaces in variants "ladder" and "self-supporting ladder (step-ladder)".
The working surfaces of the steps have the coating averting sliding of the worker's shoe's soles.
The ladder has atmosphere resistant paint coating, which ensures electrical insulation and increases service life.
